LUBRICATI NG -ECCENTRIC.

SPECIFICATION forming part of Letters Patent No. 276,885, dated May 1,1883. Application filed January 22, 1883. (No model.)

i To all whom it may concern:

Be it known that I, BOZ'IL S. ROY, of Worcester, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Lubricating'Eccentrics; and I declare thefollowing to be a description of my said invention, sufficiently full,clear, and exact to enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, which form apart of this specification.

The object of my present invention is to provide a practical andefficient means for the self-lubrication of eccentrics and theirsurrounding straps without increase in their dimensions or the additionof projections or protuberances, so that such eccentrics can be operatedand lubricated in close proximity to each other or adjacent partswithout interfer ing. This object I attain by mechanism constructed asshown in the drawings and hereinafter described.

In the drawings, Figure 1 is an end view of my self-oiling eccentric.Fig. 2 is a side and sectional view of the same, and Fig. 3 is a sec.tional view of the self-oiling eccentric on a plane perpendicular tothe supporting-shaft.

In the references to the drawings, A denotes the supporting shaft, onwhich the eccentrics are mounted. B denotes the eccentric plate or disk.(3 indicates the strap and 0 its end loop. The bearing-surfaces betweenthe eccentric B and surrounding strap 0, I make self-lubricating bycombining therewith an oilwell, m, formed within the casting or body ofmetal of which the parts are made. Said well an is furnished with aconduit leading to the surfaces, in which is arranged a wick, m, forregulating the flow of oil to the surfaces to be lubricated, and asuitable opening having a screw plug or stopper, n, is provided for theconvenient introduction of oil into the well or cavity m when required.By this method of constructing eccentrics and their connectingstraps Iavoid lateral projections beyond the usual thickness of the eccentricdisk or sur-- rounding parts, and obviate any liability of would occurwith an attached oiler by reason of the irregular throw of eccentrics.It'also permits of eccentrics being operated in close proximity to eachother, or to adjacent parts of mechanism without interfering therewith,while it provides for constant lubrication of the surfaces, thuspreventing excessive wear, and allowing of the straps being kept soclose and tight as to prevent rattling even when operating at highspeeds. The self-lubricating eccentrics of the construction describedmay be used on various classes of machinery with beneficial results andgreat practical economy and convenience.

In constructing the eccentrics the conduit from the oil-well to thebearing-surface should be arranged in such position that the end 'ofthewick on will stand above the level of the oil within the reservoir atwhen the machinery is not running. (See dotted line, Fig. 3.)

If the strap-arm O is to work in vertical position', the wick can bearranged within a tube inserted from the lower part and extending upinto. the cavity or reservoir sufficiently far to carry the end of thewick above the surfacelevel of the oil, the tube runninginto the cavityin the manner indicated by dotted lines}.

What I claim as of my invention, and desire to secure by Letters Patent,is-

The combination, with the bearing-surfaces of the eccentric B and itssurrounding strap (J, of the oil well or reservoir m, formed within thethickness of metal of which the parts are made, substantially as shown,with the lubricating wick or packingm, leading to the saidbearing-surfaces, for regulating the passage of oil from the reservoirto said surfaces, as set forth, whereby said eccentric is renderedselflubricating without increasing its lateral dimensions. g
